New research by a team of scientists at the University of Western Australia (UWA) shows plants have long-term memory. This adds to a body of research that has shown plants have high-level mental processes, including the ability to feel fear and happiness, the ability to communicate, and even the ability to read your mind.

Prince Charles once said he talked to plants and they responded. As an Economist article about the new plant memory research points out, Prince Charles faced some ridicule for his statement, but perhaps he will soon be vindicated.

Here’s a look into the minds of plants.

1. Plants Have Long-Term Memory: New Research

Dr. Monica Gagliano led the UWA study, which was published in the journal Oecologia.

She and her team dropped potted Mimosa pudica plants onto cushioning foam from a height that would shock the plants, but not harm them. Mimosas were chosen for a unique attribute: they close their leaves when threatened, thus it is easy to observe their reaction to stimuli.

What the researchers wanted to see is whether the plants were able to learn that the shock wouldn’t hurt them. They also wanted to see if the plants could remember that fact over an extended period of time.

The plants stopped reacting after a few drops, showing they had learned the action was not dangerous. The researchers made sure it wasn’t simply that the plants were fatigued and could no longer react; they applied a different stimulus to which the plants instantly reacted.

The tests were carried out on multiple plants over various time periods.

Some plants were left undisturbed for 28 days after an initial test of a few drops. After so many days, the plants still remembered the lesson they had learned and did not react to the drop, though they did react to other stimuli.

How Do Plants Think Without Brains?

Though plants do not have the brains and neural systems observed in other organisms with higher mental faculties, researchers are starting to hypothesize alternative systems. For example, the Economist explains, plants have well-formed pathways through which they may transmit information in the form of electrical signals.

2. Plants Have Feelings

The late Cleve Backster made an astonishing discovery in 1966 that started the trend of people talking to their houseplants.

Backster was a former CIA lie-detector specialist who developed polygraph techniques still in general use today by the U.S. military and government agencies. He performed an experiment on dragon pot plants (Dracaena) detailed in the book “The Secret Life of Plants.”

He got two Dracaenaplants and connected one of them to a lie detector. He had a person stomp the other plant. When this action was performed, the polygraph showed the plant that witnessed the stomping registered fear.

Backster took it further. The plant that had registered fear was tested again. Multiple people walked into the room where the plant was, including the person who had stomped the other plant. The polygraph showed no reaction to the other people, but when the person who had stomped the plant walked into the room, it again showed fear. It seemed to recognize this person.

Plants experience happiness when watered, Backster found, and they even have the ability to read human minds.

3. Plants Can Read Minds

Once, when Backster was thinking of what experiment to try next, he thought of burning a plant’s leaves to see its reaction. Just as he had the thought of harming the plant, the polygraph showed the plant react with fear.

Backster’s findings have been reproduced by others, including Russian scientist Alexander Dubrov and Marcel Vogel, who was at IBM at the time of his studies.

4. Plants Can ‘Talk’

Plant communication is a growing field of study. Dr. Gagliano has conducted recent research on the topic. In a study published in the Oxford Journals in 2012, Gagliano explained that it has long been known that plants produce sound waves.

Many have thought these sound waves to be accidental by-products of a plant’s reaction to dehydration, rather than intentional communications. But Gagliano isn’t so sure.

She looked at the ways the plants communicate. The widely understood process that creates sound waves is called cavitation. It happens when plants are dehydrated and the water column is stressed. Gagliano said, however, “The acoustic signals emitted by plants are so numerous that it always seemed extremely unlikely that each acoustic event was attributable to cavitation alone … and in fact, recent evidence now indicates that plants generate sounds independently of dehydration and cavitation-related processes.”

She cited research that shows some of the sound waves may be created by a largely stable bubble system of the xylem conduits.

“Although the proximate and ultimate mechanisms used by animals to sense their environment and communicate with each other have long been the subject of intense scientific interest, the study of plant communication exists, but is still not as advanced and recognized,” Gagliano wrote. “This is particularly the case for plant bioacoustics; and it is surprising, when we consider that the ability to sense sound and vibrations is a phylogenetically ancient sensory modality behind the behavioral organization of all living organisms and their relationship with their environment.”

Maybe, the ability to communicate is one of the defining characteristics of life. Interesting article!

Sucks to be a vegetarian. All those years of thinking they were better. Ahwell, back to the pack with you!

These are fantastic claims. Have they been peer reviewed?

No, reacting does not mean they have a conscious and think or feel. Next they will tell us ice/water is alive because it reacts to temperature; or soil is alive because it can get wet or dry. Next they will tell us our computers are alive too. Ultimately I’m a christian…god did not give the breath of life to plants. He did to animals. It’s also interesting many or most of our edible plants have a limited life span..if you left a carrot in the ground all winter it would freeze; pea pods would dry up and fall out of the pod, fruit would rot or fall off the tree and rot. I wonder if rotting or being eaten hurts an apple more?

Well I don’t know about computers being alive, but I’ve heard people say theirs “has a mind of its own”. There are billions of people worldwide worshipping computers everyday, staring lovingly at them, obeying their every command and asking themselves “what would facebook do?”. Perhaps all that worship will eventually be rewarded with some miraculous tears flowing, like there was at those weeping statues.

As it so happens, water is alive (if you look under a microscope you will find millions of tiny organisms living in the water – even ice!). Same for soil.

Just because it does not say anything in the bible about plants having conscious thought, does not mean it is not so. The bible is not nearly comprehensive enough to encompass everything about the world and the meaning of life. A few hundred years ago Christians still believed and were adamant that the earth was flat…

Why would plants being conscious offend your Christian views?

By the way, everything has a limited life span – that does not mean it cannot be conscious. Don’t you agree?

Eratostene measured the Earth diameter 200 years B.C. … and nobody believed the Earth was flat when Columbus wished to go to India going to west. The controversia was about the exact dimension of the Earth, and Columbus was wrong (buth lucky to find America in between). If the texts you find your information contain such wrong tales… well… why not so nice things about thought of plants?

Plants always die under my watch. I must not have told them I love them enough.

: (

Aww…all they need is a good space, food, water and some attention. What they give in return is a wholly unique symbiotic relationship unlike anything else you might share space with.

And bonus…they love political scandal updates! They never tire of the coverage.

AskandTell

LOL…you know me too well Kon. Kind of spooky.

I wonder why my plants never told me they were thirsty, and waited until I noticed by chance that they were half dead.

I love my plants. I have about 30 including a few trees I bring in every year. Keeps the house smelling fresh and clean.

Even with no proof, it should be accepted that plants have life and should be treated with respect and care. I, personally, believe that plants are a higher form of life than animals because they do not consume other life to sustain themselves. They obtain their energy from the sun. I also think that the meaning of life is for us to learn how to sustain ourselves without consuming other forms of life. So I agree that being a vegetarian isn’t enough. If you’re asking yourself “how is that even possible?” look up sun eating. It is said that its possible for the human body to obtain energy directly from the sun through our eyes, and that’s the real purpose of our pineal gland. Sounds crazy at first, but scientifically makes sense after doing the research. I have been looking at the sun directly for a while now, and my hunger has diminished quite a bit. I eat very little and feel healthier than ever.
